Abstract
In a cyanoalkylation process involving the reaction of a cyanoalkene compound such as acrylonitrile with a compound containing a labile hydrogen such as ethylene glycol, to form a cyanoalkylated product such as 3,3'-ethylenedioxy-bis(propionitrile), the reaction is carried out in the presence of cyanoalkylated product in addition to the cyanoalkylated product which is formed in situ by reaction of the reactants. High yields of cyanoalkylated product and low formation of by-products are obtained.
